So finals are finally over, whichcmeans I can finish my 300g project. One of the last things I need to do is attach a piece of vinyl tubing to the nozzle beneath my bulkhead...but I can't get the bloody thing to fit. I've tried holding the tubing next to the coil in my oven, using water as lubricant... I'm out of ideas. This is frustrating. None of my local stores sell standard, clear vinyl tubing in the size I need. The hot tub hose is alleged to be the correct size.
